Huang di's Four Classics introduces the first full-scale Yin-Yang theory. The ancient idea of Yin-Yang could be classified systematically throughout Huang di's Four Classics and make itself the cause of creation, movement, and variation. The Tao of essence and Reason-Law(理法) is a single 'One'(一) and completes the reality of Tao adopting Yin-Yang as an elementary. The elementary of Yin-Yang has rules and laws and then the Tao manifest itself through Yin-Yang. The features of Yin-Yang theory in Huang di's Four Classics are placed on the explanation of the structure of the universe embodied as class and system. The class and system are the structured worlds in the space based on the upper and lower sides Yin-Yang idea(上下陰陽觀). It means the system by Yin-Yang theory, corresponding to the flat structure of the Sky and the Earth mentioned in Gaitian theory, one of the ancient theory of the universe structure. By adopting Huang di's Four Classics' Tian-zhi Yin-Yang theory(天地陰陽論) and developing the class system in human bodies, The Hwangjenegyeng appreciates human bodies as a whole. In addition, by applying Four seasons Yin-Yang theory not only to human bodies but also to the space of Liu-he(六合) and the time of Four Seasons(四時), it developed Yin-Yang theory of Huang di's Four Classics more abundantly and embodied Yin-Yang theory in many fields including physiology, pathology, diagnostics, and prescriptions.

Objectives : Based on the analysis of Yin-Yang[음양] characteristics and symptoms, each person is classified into Yin-Yang. Also the validity of the result is statistically analized. Methods : From Feb. to May. 2003, the data were collected through a questionnaire given to 690 patients. The questionnaire was composed of 34 items which were about personality, habit, sweat, response to coldness, thirst, bowel, urine, physical shape, and menstruation for women only. SD(Semantic Differential Technique) used for each item, each item is measured as a contrast of two opposite symptoms. Reliability analysis was used to select items and categories. Based on means of items in each category the Yin-Yang index was developed. The validity of Yin-Yang index was investigated using classification and clustering analysis. In statistical analysis, SPSS V10.0.7 PC was used. Results : The obtained results are summarized as follows: 1) We constructed Yin-Yang index based on the middle point of the sum of categorical means. Then we classified each person into Yin or Yang. 2) To investigate the validity of the distribution of personal Yin-Yang degree, the crosstabulation of results from clustering and classification was used. The hit ratio for classification was much higher than Maximum Chance Criterion($C_{max}$), and concurrence in crosstabulation was successful. Therefore we can infer that the distribution of Yin-Yang was valid. Conclusions : Based on Yin-Yang characteristics and symptoms, we was analyzed personal degree of Yin-Yang, and confirmed the validity of its distribution. Therefore this index can be used further for Bian-Zheng [변증] and classification of the constitution.

With regard of YinYang and Five Elements Theory, predominance of Yin or Yang is a key point to discuss Nourishin Ying or Reinforcing Yang. There are two major branches about studying predominance of Yin or Yang. Zhu Danxi advocated the theory that Yang was always in excess while Yin was often deficient, and thus belonged to the School for Nourishing the Yin. Zhang Jie-bin advocated that Yang is easily deficient while Yin is easily sufficient. It seems that they studied Wang Bing's 'Ministerial fire rule on all thing instead of Imperial Fire' and right Kidney Mingmen theory in Nan Jing, which are both related to the First Yang in the Book of Changes and say Mingmen fire is the host of the body. Zhu Danxi insisted that Mingmen fire was easily in excess and likely to become pathogenic fire while Water phase was easily in deficiency, so the doctors should nourish Yin and suppress Yang. Zhang Jie-bin said that Mingmen fire is vulnerable so the doctors should fortify yang and reinforce Mingmen fire. Suk Gock Master Lee thought that the Book of Changes and Nei Jing had a viewpoint of Fortify Yang as regards of some distinguished Physicians' articles about predominance of YinYang. The author's going to discribe Suk Gock's Fortify Yang Theory with viewpoints of Nei Jing and the Book of Changes.

The most famous thought of Dongjungseo's must be 'the Sky-Earth Response Theory.' The theory includes the Same 'Gi' Correspondence(the Same Category Homology) and explains the relationship between the nature and the men based on Yin-Yang. This theory, commonly studied by the scholars of the political science, however, has been constituting the foundation of the oriental medicine. Also, he insists many other theories related to Yin-Yang including the natural calamity, the treatise of human nature, the name and reality, and the national school of Confucianism, etc. This paper covers the Yin-Yang theory, particularly with regard to ethics. politics, human nature of Dongjungseo, and the comparison of his Yin-Yang and that of the Emperor Inner Cannon. Dongjungseo insists on the harmony of Yin-Yang just only in the area of health care, excluding other areas such as state and family governance. However, in contrast, he asserts the Yang central idea for what he defined as the order of a family, a society and a state. This presents his contradiction and logicality. In the last part of this paper, his logical flaws would be discussed and analysed. However, he is a lucky scholar, because his Yang central idea has been successfully governing peoples for a long time, despite such imperfection and contradiction in his studies.

Cho Heon Yeong's 'Tongsokanuihagwollon' is an introductory and essential book on Traditional Korean Medicine(TKM), and now we can nearly take it as classic. It contains almost whole contents of TKM : physiology, pathology, herbology, meridian & acupoint, internal medicine, diagnostics, formula science, etc. He wanted to help people get TKM services easily on their own through this book. In the first chapter following the introduction, he inserted Yin-Yang theory, and his lecture on Yin-Yang theory continues for 88 pages, taking 17% of the whole book. Yin-Yang theory chapter is composed of 14 parts which tells about concept, definition and meaning of Yin-Yang, change of Yin-Yang according to time, season, constitution, body region, meridian, herb, etc. Last part refers to disharmony & dysfunction of Yin-Yang in body, so he showed both theoretical and clinical view of Yin-Yang theory. He wrote some quotations from the book 'Complete Works of Jingyue(景岳全書)', 'Huangdi's Internal Classic(黃帝內徑)', 'Introduction to Medicine(醫學入門)', etc. He tried to explain easily about Yin-Yang theory with modern but rough language of science. He seemed to already know clearly that without modern science TKM cannot progress and will soon be overwhelmed by western medicine, and acted his own way to spread spirit of TKM in the period of rapid change & conflict between two civilizations.

1. Objectives This paper was written in order ro understand the conception on YangQi and YinQi in Sasang Constitutional Medicine. Specially that were focused on the discourse of the symptoms and diseases. 2. Methods We analysis YangQi and YinQi in Gabobon(甲午本) and Sinchukbon(辛丑本) of ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$ 3. Results and Conclusions The symptomatic-pharmacology of Soeunin and Soyangin was base on the master of reserving life(保命之主). YangQi is ascending Qi and YinQi is descending Qi. that conception is Qi of the large and small organ. And that is appeared hot or cold Qi in body. The influential competition of YinYang is focused on primordial Qi(正氣) of small organ in Gabobon. And focused on small organ's the primordial Qi of the exterior disease and large that of the interior disease in Sinchukbon. YangQi is divided to physiological that and patholgical that at the discourse on the Soyangin’s interior disease in the Sinchukbon. Because YinQi is in proportion to physiological YangQi and inverse proportion to pathological YangQi, physiological that is similar to weak and strong of YinQi that is the master of reserving life. So ascending Yang of Soyangin is more correct as ascending physiological that. YinQi is not divided to physiologica that and patholgical that at the discourse on the Soeumin's interior disease in the Sinchukbon like Soyangin's that. But there is more reasonable that divid physiological YinQi and patholgical that. So descending Yin of Soeumin is more correct as descending physiological that.

Objectives The purpose of this study was to enhance the understanding of Yin and Yang poison by examining and comparing the views of Je-ma Lee and the medicine scholars before Je-ma Lee, including Zhang Zhongjing. Methods We examined and compared the contents related to Yin and Yang poison in 『Essential Prescriptions from the Golden Cabinet (金匱要略)』, 『Donguibogam (東醫寶鑑)』, and 『Donguisusebowon (東醫壽世保元)』. Results and Conclusion In 『Essential Prescriptions from the Golden Cabinet』, Zhang Zhongjing described the symptoms of Yin and Yang poison respectively, but could not suggested each prescription. In 『Donguibogam』, there were several prescriptions for Yin and Yang poison, respectively. In 『Donguisusebowon』, Yang poison belonged to the Soyangin and Taeeumin disease, Yin poison belonged to the Soeumin disease. Je-ma Lee emphasized that interior heat, which has grown suddenly should be controlled quickly for treatment of Yang poison in Soyangin and Taeeumin. And, in order to treat Yin poison caused by chronic course in Soeumin, Ginseng should be used a lot to help the Yang energy. Also, it is a better treatment to take the medicine ahead of time before the disease develops into Yin poison.
